emDOC: Innovative Electromagnetic Clutch for Enhanced Comfort

The emDOC electromagnetic dog clutch from HOERBIGER combines the advantages of a mechanical clutch with the precision of an intelligent electromagnetic actuator, enhanced by a position-sensing sensor. This smart 3-in-1 solution operates without wear and tear, saving space, weight, and costs.

The innovative HOERBIGER emDOC is an efficient On/Off clutch designed for safe torque transfer, ideal for use in hybrid and electric drivetrains. It can serve as a connect/disconnect application to decouple unused drivetrain components, such as a secondary axle. Other applications include multi-gear transmissions, as well as parking and differential locks, where the emDOC prevents wheel spin. The removal of external mechanical components reduces the number of parts, saving installation space, weight, and cost.

Versatile design and flexible use

The HOERBIGER emDOC stands out for its scalability and adaptability. Unlike conventional systems that require a shift fork and a gear reduction for the actuator, the emDOC offers a compact, all-in-one solution with integrated actuation. It can be customized to different voltages ranging from 12 to over 48 volts, depending on customer requirements.

Smart design and reliable performance

The emDOC system features an intelligent design for precise control. It consists of a mechanical claw system for torque transmission, combined with a mechatronic system that includes an electromagnetic actuator and a position sensor. When voltage is applied to a copper coil, it generates a magnetic field that moves the coupling sleeve into the desired position. Because the system does not use permanent magnets, fewer iron particles adhere to the components, ensuring reliable, interference-free operation.

Thanks to the full integration of the actuator into the claw system, the system switches quickly and efficiently. The contactless operation reduces wear and ensures precise positioning of the coupling sleeve over its entire lifespan. The shifting operations are performed directly on the coupling sleeve, ensuring exact positioning from the first to the last shift.
